Suppose you are a product engineer for a tool manufacturing company, and want to investigate the strength of several new prototype redesigns of one of your drills. You have 12 new drill designs and would like to include a control group also of the original drill design. Your firm has decided to sample 414 drills overall in the analysis, split evenly between each product design and one control group for the original drill. Using this information, if you were to conduct an ANOVA test based on a quantitative measure of the drill's performance, what is the degree of freedom associated with the variation within groups (SSE) in this analysis (denominator degree of freedom)?

Suppose you are a product engineer for a tool manufacturing company, and
want to investigate the strength of several new prototype redesigns of one of
your drills. You have 12 new drill designs and would like to include a control
group also of the original drill design. Your firm has decided to sample 414
drills overall in the analysis, split evenly between each product design and one
control group for the original drill. Using this information, if you were to
conduct an ANOVA test based on a quantitative measure of the drill's
performance, what is the degree of freedom associated with the variation
within groups (SSE) in this analysis (denominator degree of freedom)?
